Title: Universal-type interruption closure for apparatus for bending glass sheets
Inventor: HAGEDORN FLOYD T
IPC: C03B23/03
Filed: 1986-09-23
Granted: 1991-03-12
Abstract: ABSTRACT OF THE DISCLOSURE    An interruption closure apparatus for closing an interruption in a glass bending shaping rail includes a rail segment attached to one side of a plate and a universal joint attached to an opposite side of the plate. The universal joint is also attached to one end of an arm which in turn is rotatably connected to a shaft for rotating the rail segment into and out of an interruption in the shaping rail.  A stop member attached to the arm limits movement of the plate to prevent rotational misalignment with the interruption in the shaping rail.  A plurality of screws are threaded through apertures in the plate into contact with an under surface of adjacent portions of the shaping rail when the rail segment is in the interruption.  Rotation of the screws permits the positioning of an upper surface of the rail segment with respect to an upper surface of the adjacent portions of the shaping rail to provide an uninterrupted smooth edge portion in a glass sheet being formed on the rail.

Title: Opto-electronic directional switch
Inventor: WHITE IAN H
IPC: H01S3/101
Filed: 1987-03-09
Granted: 1991-06-11
Abstract: ABSTRACT            OPTO-ELECTRONIC DIRECTIONAL SWITCH      An opto-electronic switch which shows a good signal rejection ratio between modes is also of particularly small dimensions.     The switch comprises a semiconductor laser 1 having four contacts 12, 12', 13, 13' which provide gain guiding under two stripe windows 18, 19.  By varying the bias currents supplied to the individual contacts 12, 12', 13, 13', or by inputting optical control signals to the waveguiding channels under the stripe windows 18, 19, different configurations of optical output from the laser 1 can be achieved.  The two contacts, 12, 12' and 13, 13', associated with each stripe window 18, 19 are effectively a single stripe contact with a discontinuity.  It is thought that diffractive transverse coupling at the discontinuity allows the use of a shorter device than in known directional switches.  With feedback, the switch operates as a memory device.     The switch finds particular application in optical communications, for instance in signal routing.

Granted: 1991-08-13
Abstract: ABSTRACT      Selective mono- or di-amination of alkanediols is controllably obtained by catalytic reaction with secondary amines at moderate temperature and autogenous pressure, by selection of the catalyst employed.  Ruthenium complexes compounded or admixed with selected organic phosphines, such as triphenylphosphine, favor high yields of alkanolamines, while ruthenium complexes in the absence of organic phosphines favor production of alkylenediamines.  Iridium complexes with or without organic phosphines in admixture or chemical combination, also promote production of alkylenediamines.

Abstract: OPTICAL MICROPRESSURE TRANSDUCER            Abstract of the Disclosure A thin diaphragm receives pressure across one side and faces a beam splitter on the other side. The beam splitter is integrally attached to the diaphragm and serves as a local optical reference plane for the entire assembly.  A small cavity is formed between the diaphragm and beam splitter. Coherent light from a light source is partially reflected at the beam splitter.  The remainder of the light is reflected from the diaphragm.  The reflected beams recombine at a detection point and form an interference pattern.  The phase difference between the reflected beams is a function of the amount of deflection of the diaphragm. The interference pattern being indicative of the deflection of the diaphragm is received by a light detector.  Optical calibration of the assembly is a function of the distance between the diaphragm and beam splitter which remains as predefined because the beam splitter is integral with the diaphragm.  A vent in the small cavity enables the diaphragm to sense small pressures with increased sensitivity. Fiber optics enable use of the assembly in high temperatures.  The diaphragm is fabricated by micro-machine techniques to achieve dimensions for the various applications.  The micro-dimensioned diaphragm is sensitive to dynamic and static pressure.  The measurement of deflection obtained by placing a known load across the diaphragm enables determination of the mechanical properties of the diaphragm material.  Detection of the thermal expansion of the unit as well as deflection of the diaphragm enables a sensed pressure measurement as a differential between the detected thermal expansion and deflection.

Abstract: ABSTRACT             METHOD, SYSTEM AND APPARATUS FOR PRODUCING     POWERFUL SEISMIC ENERGY IMPULSES BY IMPLOSION USEABLE              IN WELLS IN THE EARTH                 Inventor:  Stephen V. Chelminski A method, system and apparatus for producing power-ful seismic energy impulses by implosion of an imploding free piston positioned in a container which is adapted to be lower-ed down into a well in the earth to facilitate the collection of well surveying information about the geological formations of the earth in the vicinity of the well.  Holding means main-tain the imploding free piston in an initial position or quiescent state, trigger means suddenly release the holding means to cause the free piston to accelerate rapidly from its quiescent state thereby producing a powerful impulse by implosion damping means arrest the movement of the imploding free piston, and operating means return the imploding free piston to its initial position after completion of its rapid acceleration and damped deceleration.   After the imploding free piston is returned to its initial position, the apparatus may be triggered again, as desired, to produce addi-tional powerful impulses by implosion.   The self-contained apparatus includes a reversible electric motor and reversible hydraulic pump with first and second hydraulic-liquid-containing bladders.  The first bladder transmits the powerful implosions into the ambient liquid in the well, and the second bladder serves as an expansible hydraulic reser-voir and as an ambient pressure compensator for all operating parts including the motor.   The operating means and the trigger means are hydraulically actuated;  the imploding free piston is decelerated by hydraulic damping, and hydraulic liquid cools the motor.
